In the intricate world of chemical synthesis and pharmaceutical quality control, understanding the utility of specific compounds is crucial for researchers, formulators, and procurement specialists. 3,3'-Diiodo-L-Thyronine (CAS 4604-41-5), also referred to by its IUPAC name O-(4-hydroxy-3-iodophenyl)-3-iodo-L-tyrosine, stands out due to its dual significance. As a fine chemical intermediate, it offers unique structural properties for organic synthesis, while its role as an impurity standard for critical medications highlights its importance in ensuring product safety and efficacy. For those looking to buy this compound, partnering with a reputable chemical manufacturer is key.

The Dual Role of 3,3'-Diiodo-L-Thyronine

3,3'-Diiodo-L-Thyronine serves two primary functions within the chemical and pharmaceutical industries:

  • Synthesis Intermediate: The iodine atoms and the amino acid backbone of this molecule make it a valuable intermediate in the synthesis of more complex organic compounds. Researchers in medicinal chemistry and materials science might utilize its structure as a starting point for creating novel molecules with specific biological activities or material properties. When you buy this intermediate, you're acquiring a precise chemical building block.
  • Pharmaceutical Impurity Standard: Perhaps its most critical application is its classification as a Levothyroxine Impurity J. Levothyroxine, a synthetic thyroid hormone, is a vital medication. Pharmaceutical manufacturers are legally obligated to monitor and control impurities in their active pharmaceutical ingredients (APIs) and final drug products. Having a high-purity reference standard like 3,3'-Diiodo-L-Thyronine is essential for analytical chemists to develop and validate methods for detecting and quantifying this specific impurity, ensuring the quality and safety of Levothyroxine.

Procuring CAS 4604-41-5: What Buyers Need to Know

For professionals seeking to purchase 3,3'-Diiodo-L-Thyronine, especially from manufacturers in China, several considerations are paramount to ensure a successful procurement:

  • Purity and Specification Adherence: The compound's intended use dictates the required purity. For impurity standards, >99% purity is often a necessity. Always obtain a detailed Certificate of Analysis (CoA) that specifies the purity, any identified impurities, and the analytical methods used (e.g., HPLC, NMR).
  • Supplier Expertise: Engaging with manufacturers who specialize in fine chemicals and pharmaceutical intermediates ensures they understand the critical quality attributes. A reliable supplier will have consistent production capabilities and rigorous quality control systems.
  • Technical Support and Documentation: Beyond the CoA, access to technical data sheets (TDS), Material Safety Data Sheets (MSDS), and responsive customer support is invaluable for safe handling and effective utilization.
  • Pricing and Lead Times: For ongoing research or production needs, understanding the pricing structure for different quantities and the typical lead times for delivery is essential for effective project planning. Requesting a quote for your specific needs is the first step.
